GateTest vs GitHub Code Scanning
The Complete QA Platform

GitHub Code Scanning (CodeQL) is a well-engineered security tool with one job: finding known vulnerability patterns. It’s good at that job. But security is one of 90 quality dimensions your code needs — and GitHub Code Scanning covers exactly one of them.

The complete picture

Same workflow, 67x more coverage

GateTest posts commit statuses and PR comments in exactly the same format as GitHub Code Scanning. The developer experience is identical — install the GitHub App, push code, see results on the PR. But instead of security-only CodeQL alerts, you get 110 modules: security, performance, accessibility, AI safety, visual regression, and more.

AI code review CodeQL can't do

CodeQL works from a database of query patterns. GateTest sends your code to Claude for semantic reasoning — understanding what the code intends, identifying logic bugs, spotting off-by-one errors in financial calculations, flagging race conditions in auth flows. Pattern databases can't catch logic errors. AI can.

Auto-fix, not just alerts

GitHub Code Scanning shows you security alerts. You investigate, understand the issue, write the fix, test it. GateTest writes the fix and opens a pull request. The Scan + Fix tier covers both finding and fixing — security issues, code quality problems, configuration misconfigurations. The Forensic Scan tier adds attack-chain correlation, a board-ready CISO report, and a CTO-readable executive summary on top. Mutation testing and chaos / fuzz pass also ship via the GitHub Action where a CI runner is present.

Host-agnostic by design

GitHub Code Scanning is permanently tied to GitHub. GateTest's HostBridge architecture means it works across git hosts — GitHub today, Gluecron and others as the ecosystem evolves. If you ever migrate away from GitHub, your quality gate moves with you.

Frequently asked questions

Does GateTest work alongside GitHub Code Scanning, or replace it?

GateTest can replace GitHub Code Scanning entirely — it posts the same commit statuses, creates the same PR comments, and covers all the security patterns CodeQL finds plus 60+ additional quality dimensions. If you already have GHAS and want to keep it, GateTest adds everything GitHub Code Scanning doesn't cover (performance, accessibility, visual regression, chaos testing, AI code review, and more).

GitHub Code Scanning is included in my GitHub plan. Why would I pay extra for GateTest?

GitHub Code Scanning (CodeQL) is a security-only tool with a well-defined scope: known vulnerability patterns in your code. It has zero coverage of performance, accessibility, visual regression, mutation testing, AI safety, N+1 queries, datetime bugs, money/float precision, feature flag hygiene, or any of the 40+ other dimensions GateTest covers. The cost of one accessibility lawsuit, one performance-related churn, or one money-float audit exceeds a year of GateTest scans.

Does GateTest post commit statuses and PR comments like GitHub Code Scanning does?

Yes — identical workflow integration. Install the GateTest GitHub App once, and every push gets a commit status (pass/fail) with a link to the full report. Every PR gets a formatted comment with per-module results, severity counts, file references, and line numbers. The developer workflow is indistinguishable from GitHub Code Scanning — but with 110 modules instead of CodeQL's security-only scope.

GitHub Code Scanning is free for public repos. Does GateTest offer anything similar?

GateTest's pricing is per scan ($29 quick / $99 full 110 modules). There's no subscription or per-seat billing — a public-repo open-source project pays exactly the same as an enterprise. We don't currently offer a free tier, but $99 for a full 102-module scan including AI code review is substantially cheaper than what GitHub Advanced Security costs at enterprise scale.

Does GateTest work with repos on git hosts other than GitHub?

Yes. GateTest was built with a host-agnostic HostBridge abstraction. It supports GitHub natively and Gluecron via the Signal Bus. Support for additional git hosts is in the roadmap. GitHub Code Scanning is GitHub-exclusive.

Can GateTest auto-fix the issues it finds?

Yes. The Scan + Fix tier ($199) creates a pull request with code changes that fix the issues found. GitHub Code Scanning shows you security alerts and leaves fixing to you. GateTest writes the fix. The Forensic Scan tier ($399) adds Claude-driven per-finding diagnosis, cross-finding attack-chain correlation, a board-ready CISO report, and a CTO-readable executive summary. Mutation testing and chaos / fuzz pass also ship via the GitHub Action (mutation: true / chaos: true) — runs wherever your CI runs.

Security is just the beginning.
